Google Creates TV White Space Map, Starts Public Spectrum Trial

There's a lot of wireless spectrum out there, but mobile devices can't take advantage of some of it as it goes towards other uses. There is a lot of unused spectrum though, and Google wants to free it up.

Google.org, the company's philanthropic arm, is working with other tech companies to create a database of unused TV white space. This database would allow future devices to tap into spectrum that's not being used by someone else. The practice is called spectrum sharing, and it would allow mobile devices to share the air waves with other devices and services on this particular band.

Here's how Google explains it:

Spectrum is a globally finite resource, which makes it crucial that it be allocated and shared as effectively as possible. The demand for spectrum is growing, and more people and devices need spectrum in the same place. Having a place where people can see what spectrum is available allows people to share, which enables more technology and devices to connect using an increasingly busy medium. This helps avoid conflict between devices using the same band.

As part of its bid to become a database administrator of this TV white space, Google has partnered with the FCC to create a map of all the available TV White Space in the U.S. The company is inviting multiple stakeholders to "test and provide feedback on the database."
